[PATCH v2 2/2] ssh signing: clarify trustlevel usage in docs

[Fabian Stelzer <fs@gigacodes.de>]

facca53ac added verification for ssh signatures but incorrectly
described the usage of gpg.minTrustLevel. While the verifications
trustlevel is stil set to fully or undefined depending on if the key is
known or not it has no effect on the verification result. Unknown keys
will always fail verification. This commit updates the docs to match
this behaviour.

 SSH has no concept of trust levels like gpg does. To be able to differentiate
 between valid signatures and trusted signatures the trust level of a signature
 verification is set to `fully` when the public key is present in the allowedSignersFile.
-Therefore to only mark fully trusted keys as verified set gpg.minTrustLevel to `fully`.
-Otherwise valid but untrusted signatures will still verify but show no principal
-name of the signer.
+Otherwise the trust level is `undefined` and git verify-commit/tag will fail.
